You are right both pagodas look alike but while reading through your post I also noticed the difference of the carving. In my opinion the structure and appearance not much differ from one to another. But I like the one with carving and you may know why, I love Artistic works and especially the works of Old Masters, that is national treasure and heritage. I love how Korean Nations looks after its heritage with full respect and love. Every time it is something new I am opening in your culture and even I know some terminology too :)
